When water flows into the ice tray to be frozen, the water is not measured in volume. Instead, the water valve is allowed to remain open for a set amount of time, and the amount of water dispensed depends on the home's water pressure. Adjusting the timing of the fill valve will increase or decrease the size of the ice cubes.
The ice maker has an adjustment screw, which allows the user to increase or decrease the length of time that water is dispensed into the ice tray. To access the screw, the front panel of the ice maker must be removed. Remove the cover, and then remove the screw that secures the front panel of the ice maker. Once the screw is removed, remove the front panel of the ice maker to access the adjustment screw.
The adjustment screw is located on the right side of the front of the ice maker. Use a flat-head screwdriver to rotate the screw. Rotate the screw clockwise to reduce the amount of water dispensed into the ice tray and counterclockwise to increase the amount of water dispensed.
When turning the adjustment screw, rotate it in quarter-turn increments. Once this is completed, reassemble the ice maker and allow the cycle to complete, which takes several hours. If further adjustment is needed, repeat the steps. The ice maker should not need to be adjusted more than one full turn. If it does, a problem in the refrigerator's water filtration system or water inlet valve is likely .
